Description

  The present invention relates to a paper fan that can be used as a fan by using cardboard as a material, cutting out the cardboard, bending it, and incorporating it.

  The conventional paper folding fan folds the base folding lines of multiple fan leaves and folds the same planes facing each other, and the base folding lines are rotated by sandwiching them between a radial folding line centered on the base point and a staggered folding line. The rotating surface has a fan shape with a small angle, and the rotating surface is alternately reversed on the front and back sides to open and close the fan leaves like a fan.

ACT 7-43948

  The conventional technology has a structure in which the same surfaces are folded face-to-face so that when viewed from one side, the front and back sides are adjacent to each other in the same direction. There is a problem that it is technically very difficult to match the hue and screen misalignment by double-sided printing. In the present invention, the problem as described above is solved.

  Centering on the trunk surface, each side of the trunk surface is made into one and the other folding line, and the rotation area is extended through the folding line, and the outside of the rotation area (the one far from the trunk surface is outside) A fan leaf is extended to the horizontal side through a closed line, and the rotation area forms an upward fan shape with a fulcrum located below as a base point, and is located away from the fulcrum. The upper end point of the closed fold line is used as a joint point, and the fan leaf above the joint point is bulged in the direction of the trunk surface to form a superposition region, and one and the other fan leaf are formed in a substantially line symmetrical shape on the left and right. Provide.

  By folding one open fold line and folding the other open fold line, only the trunk surface is reversed and turned face down, so the fans are in the same face-up state and the joints are in contact with each other and open. The open state is fixed by swapping the overlaps. By releasing the open fixed state and shifting to the refraction to the closed fold line, the rotation range is reversed and the back is turned to the back side, so that both the fans are overlapped in the same face-up state. The body can be closed.

FIG. (Example 1) It is a front perspective view of an open state assembly process. It is a transparent front perspective view of an open state assembly completion principal part. It is a perspective view front perspective view of a principal part in a closed state. FIG. (Example 2) It is a perspective front perspective view of the main part of the assembly process.

  Only the trunk surface is reversed by folding one open fold line and folding the other open fold line, so that an open state can be formed between the fan leaves facing the same direction, and the refraction of the open fold line becomes a closed fold line. By shifting, the rotation region is reversed, and by reversing the rotation region, the entire fan can be overlapped in the same direction to be closed.

  FIG. 1 is a developed front view. The material forming the main body 1 may be plastic, which is an artificial resin, but it is desirable to use cardboard as a material that can be recycled and reduce the environmental burden. The thickness and hardness of the cardboard are not limited, and are made by government agencies. It is sufficient if it has a thickness and hardness of about a postcard, and it may be a thicker and harder cardboard than a public postcard.

  If the drawing display method is described, the solid line is a cut line, the broken line is a transparent line, the alternate long and short dash line is a broken line, and the lead-out line is a solid line, but it is distinguished from a cut line by thinning the line. The folding direction of the fold line does not have to be limited, and can be freely changed by the user, but in order to clearly explain the patent contents, the folding direction is clearly specified, and the folding direction displayed by valley fold and mountain fold is I will describe it from the front. The horizontal direction is the horizontal direction, the vertical direction is the vertical direction or the vertical direction, and the front-rear direction is the front-rear direction.

  If there are two places with the same reference sign on the left and right, the left side in the unfolded state is one and the right side is the other. Symbols “a” and “b” for distinguishing one from the other are enclosed in parentheses in the drawing and are displayed as (a) and (b). When (a) and (b) are omitted, one and the other are generic symbols. And

  To describe the unfolded state of the main body 1, a vertically long (substantially) rectangular trunk surface 2 is provided at the center, and the trunk surface 2 is substantially rectangular, so that there are two folding lines 3 on the left and right sides. The left side of the fold line 3 is defined as one fold line 3a, and the right side is defined as the other fold line 3b.

  Although the rotation area 4 is extended through the open fold line 3, the rotation area 4 may be provided at one place, but preferably provided at two places, one rotation area 4a and the other rotation area 4b. The following description will be made with two rotation regions 4 that are desirable. One rotation region 4a is extended from the trunk surface 2 through one open fold line 3a which is a valley fold line, and outside the one rotation region 4a (because it is positioned around the trunk surface 2, it is far from the trunk surface 2). One fan leaf 6a is extended through one closed fold line 5a whose lateral side is a valley fold line.

  One rotation region 4a preferably has a fan shape starting from one fulcrum 7a located below, and the fulcrum 7a is the intersection of one open fold line 3a and one closed fold line 5a. However, the lower end of the one open fold line 3a and the one closed fold line 5a is not in contact with each other, and it is desirable to leave a gap 8a of about 2 to 3 millimeters, and the role of the gap 8a is to break the cardboard which is the material In addition to preventing breakage due to bending deterioration, it is also a gap for accommodating the blade thickness required when making a wooden mold for punching with Thomson.

  Since the trunk surface 2 is a vertically long rectangle, one open fold line 3a is preferably a vertical valley fold line, and one rotation area 4a has a fan shape that slightly extends in the celestial direction, so that one closed fold line 5a The top end is inclined toward one of the outer sides, and the length of the top edge of one rotation area 4a is preferably half the length of the top edge of the trunk surface 2, and the one rotation area 4a The top edge of one of the closed lines 5a is preferably the top edge of one closed fold line 5a, and one folding point 5a is defined as the area of one fan leaf 6a located above the one combined point 9a. The shape which bulges inward (stem surface direction) rather than on the extension line above the upper part, and makes the bulge area one polymerization area 10a, and combines the two fan leaves 6 having two sheets is limited. However, it may be a freely designed shape. If one is made into a heart shape, the shape of the one fan leaf 6a is basically a half shape of the heart shape, and the shape of the one fan leaf 6a is substantially a slanted ball shape when the one overlapping area 10a is combined. It is desirable to become.

  The other rotation region 4b is extended from the trunk surface 2 via the other open folding line 3b which is a mountain fold line, and the outside of the other rotation region 4b (because it is positioned around the trunk surface, The other fan leaf 6b is extended through the other closed folding line 5b whose lateral side is a mountain fold line.

  The other rotation region 4b preferably has a fan shape starting from the other fulcrum 7b located below, and the fulcrum 7b is the intersection of the other fold line 3b and the other fold line 5b. However, the lower end of the other fold line 3b and the other closed fold line 5b are not in contact with each other, and it is desirable to leave a gap 8b of about 2 to 3 millimeters, and the role of the gap 8b is to break the cardboard that is the material. In addition to preventing breakage due to bending deterioration, it is also a gap for accommodating the blade thickness required when making a wooden mold for punching with Thomson.

  Since the trunk surface 2 is a vertically long rectangle, the other open fold line 3b is preferably a vertical mountain fold line, and the other rotation area 4b has a fan shape that slightly extends upward, so that the other closed fold line 5b The top end is inclined toward the other side which is the outside, and the length of the top edge of the other rotation area 4b is preferably half the length of the top edge of the trunk surface 2, and the other rotation area 4b. The top edge of the other closed fold line 5b is preferably the top edge of the other closed fold line 5b, and the other fan leaf 6b located above the other combined point 9b is defined as the other closed fold line 5b. Bulge inward (trunk surface direction) from above the line extending upward, and the bulging area is the other overlapping area 10b, and the shape of the two fan leaves 6 combined is limited However, it may be a freely designed shape. The other fan leaf 6a is basically in the shape of a half of a heart shape, and the shape of the other fan leaf 6b is substantially a slanted ball shape when the other overlapping area 10b is combined. It is desirable to become.

  FIG. 2 is a front perspective view of the opened state assembly process. By folding one open fold line 3a and making the other open fold line 3b fold, only the trunk surface 2 is reversed, and the reversal of the trunk surface 2 brings one joint 9a and the other joint 9b closer to each other and is closed. The broken line 5 is not bent, so that the rotational area 4 and the fan leaf 6 are in one surface, the joints 9 of the two approach each other, and the body 1 is in an open state with the joints 9 in contact with each other. When the joining points 9 are in contact with each other, the other overlapping region 10b overlaps the front of one overlapping region 10a, and the connecting shape of the main body 1 is the heart shape between one fan leaf 6a and the other fan leaf 6b. become.

  FIG. 3 is a transparent front perspective view of a main part of the opened state assembly completion. One fold line 3a is valley-folded, and the other fold line 3b is fold-folded so that the one main point 9a and the other main point 9b are in contact with each other, and the entire body 1 becomes a heart-shaped open state, and the overlapping polymerization area 10 overlapped in front and back, one polymerization zone 10a is put out on the front and the other polymerization zone 10b is hidden on the back so that it meshes and is fixed at the point 9 so that the main body 1 is fixed in a heart-shaped open state. it can.

  Since the joining points 9 are engaged with each other and fixed, the entire opened main body 1 has a single plate shape, so that there is no possibility of partial peeling even with a fan.

  The main body 1 in the open state is sandwiched between the palms and fanned. The location is not limited and the user can choose freely. However, if the desired holding location is described, the lower part of the main body 1 in the open state is It is desirable to have it, and if you hold the lower part of the main body 1 and fan it, the trunk surface 2 can play a role of reinforcement, and the area of the trunk surface 2 is three-layered. Demonstrating.

  The open state of the main body 1 can be fixed by meshing the joints 9, but a location where the closed state of the main body 1 can be fixed may be provided. To fix the closed state, the top of the fan leaf 6 is fixed. It is desirable to provide the notch 11.

  The shape of the notch 11 is not limited, and may be semicircular. However, it is desirable that the notch 11 has a bent J shape, and the bending direction of the notch 11 is reversed in one and the other. One cut 11a at the top of one fan leaf 6a has a J-shape bent to the left, and the other cut 11b at the top of the other fan leaf 6b has a character-shape bent to the right. Is desirable.

  If the closing process of the main body 1 is described, returning the one superposition zone 10a to the back and returning the other superposition zone 10b to the front releases the meshing of the joints 9 and unlocks the open state of the main body 1 Is done. By releasing the fixing, the fan leaves 6 can move freely, and the revolving area 4 is reversed to the back by changing from the refraction of the open folding line 3 to the refraction of the closed folding line 5. The incision 11 which turns to the direction and the top part of the fan leaf 6 rotates to the center direction in the circumference shape centering on the fulcrum 7 by the reversal of the rotation area 4 to the back, and has the top part of the fan leaf 6. As the two approach each other, the main body 1 moves in the closing direction.

  FIG. 4 is a front perspective view of a principal part in a closed state. The open fold line 3 is a fold line that is refracted when the main body 1 is opened, and the refraction of the open fold line 3 shifts to the closed fold line 5 so that the rotation region 4 is reversed and turned to the back so that the main body 1 is closed. When the closed line 5 is refracted, the rotation area 4 is reversed and turned over, so both the inversion areas 4 are sandwiched between the fan leaves 6 and are hidden inside and visible from the outside. Since there is no state, it is shown by a broken line meaning perspective.

  The shape of the closed state of the main body 1 is not limited and may be a freely designed shape. However, a functional and desirable closed shape is a vertically long fan shape with a circular upper edge. For example, the shape of a balloon with a gondola hanging from the side is similar.

  The top of the fan leaf 6 is based on the closed state of the main body 1. When the main body 1 is in the closed state, one notch 11 a and the other notch 11 b are combined to bend both the notches 11. The built-in is fixed where the tips touch.

  The closed state of the main body 1 is stable, and there is little fear of spreading unintentionally even if there is no notch 11, and the closed folding line 5 can maintain the bending state, but also consider the case where the main body 1 is fanned in the closed state. By fixing the top of the fan leaf 6 with the notch 11, it is possible to prevent the top portions of the fan leaf 6 from separating and fluttering even when the main body 1 is closed.

  FIG. 5 is an unfolded front view. In Example 1, it is comprised only with the heart-shaped fan part 12, and since each location which comprises this fan part 12 is almost the same as that of Example 1, or a similar shape, a code | symbol and a name will also be used. . In the second embodiment, a sheath portion 13 that can be used as a storage place for making the fan portion 12 easy to hold and fix the closed state is newly provided. The sheath portion 13 is a state in which the fan portion 12 is closed. It also has a function that can be partially stored.

  If the method of providing the sheath part 13 newly added in Example 2 is described, the trunk surface 2 located at the center is extended downward, the extension region is defined as the core region 14, and the trunk surface 2 and the The same area without a boundary line is formed between the core area 14 and the boundary area between the two is described as the core area 14 below the gap 8 provided at the lower end of the rotation area 4.

  The upper portion of the core area 14 is preferably a parallel line having the same width as the trunk surface 2, and is preferably formed in a vertically long fan shape that gradually narrows below the fulcrum 7. By doing so, the winding shape of the sheath part 13 wound around the core region 14 can be formed into a vertically long fan shape.

  A folding line 15 is provided as a horizontal folding line at the lower end of the core area 14, and a sheath part 13 that is upside down is extended through the folding line 15. In Example 2, the location of the fold line 15 is the base, and the position away from the base is the first when the positional relationship of the sheath 13 is shown. By folding the folding line 15 in a mountain fold, the sheath portion 13 is folded back so that the tip of the sheath portion 13 is on the top, and the core portion is placed with the tip of the sheath portion 13 facing up. The region 14 is wound around a core to form a sheath-shaped tube (a shape in which both sides are not parallel), and the sheath portion 13 formed into a sheath-shaped tube is used as a handle.

  In order to wrap the sheath portion 13 around the core region 14 to form a sheath-shaped tube, an inner sheath surface 16 is provided at substantially the center of the sheath portion 13, and the inner sheath surface 16 extends a little in the shape of a vertically long thin fan. The a sheath surface 17 is extended on one lateral side of the inner sheath surface 16 via a fold line 24 of a mountain fold line, and a kerf 18 is formed on the center line of the a sheath surface 17. Is provided. Desirably, a b-sheath surface 20 is extended on the other lateral side of the inner-sheath surface 16 via a b-fold line 19 of a mountain fold line, and the lateral width of the b-sheath surface 20 is substantially half of the inner-sheath surface 16. The insertion piece 23 is extended to the other lateral side of the b sheath surface 20 via the insertion fold line 22 of the mountain fold line, and the tip of the insertion piece 23 adjacent to the tip of the insertion fold line 22 is pointed first. It is desirable to form the protrusion 26 by slightly projecting in the direction.

  FIG. 6 is a perspective front perspective view of the main part of the assembly process. In the first embodiment, the fan surface 12 is assembled by reversing the trunk surface 2, but in the second embodiment, the trunk surface 2 is not reversed, but the fan leaf 6 is folded and displayed in the assembly process. Yes, both of the fan leaves 6 face back, but the structure remains the same.

  The left folding line 3a, which is one horizontal side of the trunk surface 2 that is a vertically long rectangle, is valley-folded so that one rotation area 4a and one fan leaf 6a are folded back and turned to the back. By turning the right open fold line 3b, which is the other side of the surface 2, into a mountain fold, the other rotation area 4b (shown in FIG. 5) and the other fan leaf 6b are folded back and turned back. , One joint 9a and the other joint 9b are adjacent to each other, and the fan 12 is in an open state, and in the open state, the one polymerization zone 10a overlaps the front of the other polymerization zone 10b. Is not fixed, and both overlaps of the polymerization zones 10 are interchanged in front and back, so that both of the congruent points 9 are engaged and fixed. Specifically, one polymerization is performed on the back of the other polymerization zone 10b. By shifting to a state where the area 10a overlaps, both of the meeting points 9 are engaged. Open state of fanning unit 12 is fixed match.

  By folding the fold line 15 in a mountain shape, the tip of the sheath portion 13 is positioned upward and overlapped with the core region 14, and the fold line 15 functions to fold up the sheath portion 13 and raise it. However, it is necessary to fix the closed state by partially retracting the lower portion of the closed fan portion 12 by raising and lowering the sheath portion 13 that is folded in three into a sheath-shaped cylinder, In order to realize the function of moving up and down, it is desirable to place a horizontal folding line 25 on the folding line 15 as a mountain folding line. The lifting folding line 25 may be one, but an intermediate step is provided. Since the structure that can be lifted and lowered in two steps can be performed more smoothly, it is desirable to provide the two folding lines 25, and the number of the folding lines 25 may be two or more. The intervals between the folding lines 25 are equal. However, the distance closer to the fold line 15 can be reduced. Masui.

  Since the lower portion of the core area 14 has a vertically elongated fan shape, the inner sheath surface 16 that is folded to the back surface of the core area 14 can be formed into a vertically elongated fan shape. By forming the inner sheath surface 16 with the lateral side expanded by moving the side parallel to the outside, the sheath portion 13 is wound in a three-fold state with a marginal width with the core region 14 as a core. Can do.

  Since the sheath 13 is folded back, the front surface is directed to the back, so that the folding direction indicated by the mountain fold and the valley fold is described with reference to the back direction. If the process of winding 13 in a three-fold state is described, the a-fold line 24 which is one side of the inner sheath surface 16 is folded in a mountain and folded to the front of the core region 14, and the other side of the inner sheath surface 16 is folded. The b-fold line 19 which is a side is folded in a mountain and folded to the front of the a-sheath surface 17 so that the sheath part 13 is formed into a three-fold cylindrical shape. The three-folded tubular shape of the sheath portion 13 is fixed by inserting the insertion piece 23 extended on the outer lateral side of 20.

  Since the sheath 13 fixed in the shape of a three-fold cylinder serves as a handle, the main body 21 can be fanned by gripping the sheath 13 in the same manner as a fan. Since the length of the core area 14 can be changed by bending the folding line 25, the fan part 12 can be moved up and down, and the fan part 12 is opened and fanned while the fan part 12 is raised. It is possible to close the fan portion 12 and lower it, so that the lower region of the fan portion 12 is partially accommodated in the sheath portion 13 so that the closed state can be fixed.

  Since the present invention is a paper material and can be printed freely, it can also be used as a flyer or catalog as an advertising medium.
